Taxonomic Swap 20443 (Committed on 2017-02-21)

Based on synonymy in A Cumulative Checklist for the Lichen-forming, Lichenicolous and Allied Fungi of the Continental United States and Canada, Version 21, but the underlying paper is

Arup, U., U. Søchting & P. Frödén. 2013. A new taxonomy of the family Teloschistaceae. Nordic Journal of Botany 31: 16-83.

which is not available online. Arup et al. (2013) write of this new(ish) genus,

The genus has so far not been widely accepted although it is genetically well-delimited and separate from both Xanthoria s.s. and other segregates from that genus. From Xanthoria it mainly differs by the narrower lobes (except X. resendei) and from Dufourea by the narrow lobes that are rather tightly attached to the substrate.

@jwalewski and @meurkc, would you mind taking a glance at this? This is one of many changes stemming from updates to Esslinger's North American lichen list, but it ultimately comes from Arup et al. 2013. Seems appropriate to me, but it's going to cause a bit of identification churn.

I have not checked Ted's list in about 10 years...and it shows. Yup, it's gonna cause some consternation, but we will all have to keep up. I can see that many of my observations will be changing - including Xanthomendoza, Rusavskia, etc. Wow, this is gonna hurt my brain; not mention that the new name simply does not roll off the tongue...ha ha.

Thanks for connecting me to this notice. I am going to clearly have to find time to make the changes to my observations.

Thanks for taking a look. This change will update your observations automatically, and I've staged (and will be committing) many other changes based on Esslinger's latest list in the coming weeks: http://www.inaturalist.org/taxon_changes/group/Esslinger%202016

However, I'd appreciate it if you could hold off on committing more of these until we hear from our colleagues elsewhere. Some of the changes Esslinger has chosen to adopt may not sit well with the folks in New Zealand or elsewhere. That's why I tried to loop in @meurkc. Sorry I didn't make that clear in my original comment.

thx Ken-ichi - well I've come to accept that this constant taxonomic shuffling is the new norm. but it hurts this old head too. I'm not really a taxonomist and our best person to comment (who is a stickler for keeping up) is Peter de Lange @pjd1 - so for the first time I've attached a name to one of these messages and hopefully we see what his take is on this. I guess I don't mind if the system still recognises the old name when I type it in and kindly upgrades the name - and that all synonyms get captured when there is a mapping exercise :-). one of our other great shocks in recent times is ubiquitous Veronica for (nearly) endemic Hebe. shame really! and losing one of our loveliest plants from the endemic monotypic genus Kirkianella to some common or garden composite genus :-(. c

Kia Ora - in New Zealand we are following Ulrik Sochting's work - and some of the changes processed by Arup et al (2013) have been made already on iNaturalist by Jerry Cooper (e.g., Dufourea for some of the Xanthoria and Jackelixia). However, acceptance is not universal - Australian's are mostly ignoring the decisions made by Sochting's team. The New Zealand decision to follow Arup et al. (2013) follows the wishes of the late Dr David Galloway (our key lichenologist) and discussions I had with Ulrik Sochting in 2014.

In New Zealand we have had to be pragmatic and from what we have seen of Arup et al (2013) their decisions do seem to be more critically considered than the alternative system proposed by Fedorenko et al. (2009) and Kondratyuk et al. (2009).

Fedorenko, N.M.; Stenroos, S.; Thell, A.; Kärnefelt, I. and Kondratyuk, S.Y. (2009) A phylogenetic analysis of xanthorioid lichens (Teloschistaceae, Ascomycota) based on ITS and mtSSU sequences. - In: A. Thell, M.R.D. Seaward and T. Feuerer: Diversity of Lichenology * Anniversary Volume. Bibliotheca Lichenologica No. 100. J. Cramer in der Gebrüder Borntraeger Verlagsbuchhandlung, Berlin and Stuttgart, pp. 49-84.

Kondratyuk, S.Y.; Kärnefelt, I.; Elix, J.A. and Thell, A. (2009) Contributions to the Teloschistaceae, with particular reference to the Southern Hemisphere. - In: A. Thell, M.R.D. Seaward and T. Feuerer: Diversity of Lichenology • Anniversary Volume. Bibliotheca Lichenologica No. 100. J. Cramer in der Gebrüder Borntraeger Verlagsbuchhandlung, Berlin and Stuttgart, pp. 207-282.

Still as far as I can gather there is a war going on with this group of lichens between two research groups and I don't think you are going to get much stability for quite a while yet.

Thanks, Peter. That's why we try to follow authorities whenever possible, in this case Esslinger. Just wanted to make sure it wasn't going to conflict with opinions in NZ. To my knowledge we don't have many Australian lichen people, certainly none who have observed this taxon.

When you say that in NZ you have accepted Schoting's work, who are you speaking for? NZOR? If so I'll use NZOR as a guide when trying to figure out how the changes Esslinger has chosen to adopt may or may not sync up with opinions in NZ. If not NZOR, do you guys have an authoritative list of NZ lichens somewhere?

Posted by kueda about 7 years ago

Kia Ora - NZOR - when it is updated will follow Arup et al. (2013). Currently NO ONE who runs NZOR has an up to date lichen list. The only people who have one are the New Zealand Department of Conservation - we have a listing which we are using for threat listing purposes. When that list is fully revised Landcare Research will have a copy, at which stage they will enter it into Nga Tipu o Aotearoa New Zealand Plant Names Database where upon I can only assume NZOR will pick it up - as these databases are linked. That will affect all 3000+ lichens we 'think' we have here.

NZOR is I gather, after a very long hiatus being updated at the request of various New Zealand Government Departments

So with that back ground - Nga Tipu o Aotearoa New Zealand Plant Names Database has followed or started to follow the Arup et al. (2013) treatment because 1. I sent them Arup et al. (2013), 2. They wished to honour the late David Galloway's unpublished 'master list' where he followed Arup et al. (2013).

I am not sure all genera Arup et al (2013) propose / resurrect are there but I suspect so.

This is the sole reason why Jerry Cooper added some of the genera Arup et al. (2013) recognise to iNaturalist i.e. because they were on Nga Tipu o Aotearoa New Zealand Plant Names Database.

Hope that helps,

Peter
